Question

Dear Doctor, my son is currently five months old. When he was one to two months old, he occasionally had vomiting episodes, but they were not severe. From three to four months old, the vomiting situation improved, but recently, it has started again. Whether it’s immediately after feeding or three plus hours after, he vomits intermittently. The vomit resembles tofu gruel or egg flower in consistency, suggesting it is not fully digested. During vomiting, the baby seems to feel no discomfort. Additionally, his weight continues to steadily increase, and he currently weighs over 18 jin (approximately 90 pounds) and is 68 centimeters tall. What could be the reason for this? Isn’t it said that vomiting issues generally improve after three months? Why is my son vomiting again at five months old? Moreover, how much milk should a five-month-old baby typically consume?

Answer

Hello, vomiting in babies is a normal physiological phenomenon. Since infants have a horizontal stomach position and their gastroesophageal sphincter is not fully developed, their stomach capacity is small, making it easy for food to reflux. Therefore, vomiting can occur due to improper feeding or overeating.
